Hello Kannan, thank you very much for the additional background. I must say that I admire this girl and I am glad that she has a saying in her own future. She is still young (maybe not in the eyes of the Indian people, that I dont know. My own dochter is 36 and not married yet, also a career woman, but nowadays it does not matter to marry a bit later, probably even better with all the divorces going on!!)
I am not sure if the future husband will be foreigner. Ruler of her 7th house, Saturn, is in her 1st house. She is Indian, so probably the prospective husband as well. Also, now that we know this, you can see that with ruler of her 7th in her 1st, the girl wants the boy on her term. The prospective husband could also be an older man, not someone of her own age. (Saturn).
Also it means that marriage wont come at a very early age.
A foreign husband can be seen from the ruler of the 7th in the 9th house. There is no such thing in her chart. Only thing I do see, is that the ruler of the girls 9th, Venus, falls in her 2nd (support) in the sign of Libra (partnership). So maybe this means that she is looking for a husband of foreign origin who can support her financially. North Node in the 7th only means that a marriage would be good for her in horary astrology.
The mother should not worry. Her daughter knows what she wants and I find it admirable that she does not want a prospective husband to let her parents pay through their noses in order to get a husband
About the natal chart. It is best if you were to post a question in the natal astrology forum, separate from Horary. Maybe someone can help you further there. Unfortunately I have very limited time to look into natal charts at the moment and as moderator I also have to "watch "over the forum which takes time.
